General description

The Product is 6M solution of hydrochloric acid in water. Hydrochloric acid is a strong mineral acid. It participates in the synthesis of alloxan (hexahydropyrimidine-2,4,5,6-tetrone) and hydrated aluminum chloride.

Application

Hydrochloric acid may be used in the following studies:
  • Preparation of orcinolhydrochloric acid (Bial′s reagent), which is useful for the quantitative determination of sialic acids.
  • Hydrolytic decomposition of chitin.
  • Preparation of ammonium chloride.
